# HedgeDoc Flavored Markdown
|
|
|
|
HedgeDoc has its own markdown dialect which supports many features from [CommonMark][commonmark]
|
|
and [GitHub Flavored Markdown][gfm]. It also adds some new extensions and is missing some.
|
|
|
|
These tables tell you what exactly we support in HedgeDoc 1.x (HFM 1) and HedgeDoc 2 (HFM 2).

## Embeddings
|
|
|
|
HFM 1 includes support for certain embeddings of external content by using the
|
|
`{%keyword parameter %}` syntax. To increase the readability of the markdown code
|
|
we decided that HFM 2 should just use plain links if possible.
|
|

|
| [YouTube][youtube] (`{%youtube ... %}`) | ☑️ | with plain link[^embed] | | |
|
|
| [Vimeo][vimeo] (`{%vimeo ... %}`) | ☑️ | with plain link[^embed] | | |
|
|
| [Slideshare][slideshare] (`{%slideshare ... %}`) | ☑️ | removed | | |
|
|
| [Speakerdeck][speakerdeck] (`{%speakerdeck ... %}`) | ☑️ | removed | | |
|
|
| [GitHub Gist][gist] (`{%gist ... %}`) | ☑️ | with plain link[^embed] | | |
|
|
|
|
[^embed]:
|
|
The special syntax from HFM 1 is deprecated, but will still work in HFM 2. However, a plain link to the
|
|
content should be used.
|
|
|
|
## HTML
|
|
|
|
Besides the basic HTML typography elements (`<p>`, `<a>`, `<b>`, `<ins>`, `<del>`)
|
|
the following more special HTML elements are supported by some specification.
